Scaleway Elements IoT Hub Metrics

IoT Hub Metrics - Overview

Metrics report usage of your Hub and Devices.

For each metric you can choose among 5 time scales:

1 . Last 60 min: values from 1 hour ago to the last minute, aggregated per minute,2 . Last 24 hours: values from 24 hours ago to last hour, aggregated per hour,3 . Last 7 days: values from 7 days ago to last day quarter, aggregated per 6 hour,4 . Last 30 days: values from 30 days ago to yesterday, aggregated per day,5 . Last 365 days: values from 365 days ago to last 30 days, aggregated per 30 days

Metrics

Messages count

Messages count Device metric is the number of messages exchanged between the Hub and the Device during the period,

Messages count Hub metric is the sum of all messages exchanged during the period.

Any kind of MQTT packet (CONNECT, PUBLISH, SUBSCRIBE, PING, …) is counted as 1 message. The same message published to several devices counts as many recipients devices.

Device Activity and Active devices

Device activity Device metric shows when the Device was connected to your Hub,

Active devices Hub metric is the number of distinct Devices connected at least once to your Hub during the period.

A device is flagged as connected as soon as the Hub receives a valid CONNECT packet and accepts it. It is flagged disconnected after its connection has been closed. It is considered active during a period interval if it was connected at least once during that interval.

Device active state is represented with a green positive bar, while an inactive state will be represented by a red negative bar.

Examples:

Device1 connects at 9:10am, disconnects at 9:11am.
- In **Last 60 min** period, it will be counted as active for *9:10am* and *9:11am* bars.
- In **Last 24 hours** period, it will be counted as active for *9:00am* bar.
Device2 connects at 9:11am, disconnects at 10:31am.
- In **Last 60 min** period, it will be counted as active for *9:11am* to *10:31am* bars.
- In **Last 24 hours** period, it will be counted as active for *9:00am* and *10:00am* bars.
